Abstract

OBJECTIVES:

We aimed to compare clinical outcomes of octogenarians > or =80 years of age after coronary drug-eluting stent (DES) implantation.

BACKGROUND:

Although octogenarians constitute a fast-growing portion of cardiovascular patients, they are not adequately represented in current clinical revascularization trials.

METHODS:

We analyzed the data of 3,166 consecutive patients who underwent percutaneous coronary intervention (PCI) and DES implantation since March 2003. Periprocedural events, 1- and 6-month clinical outcomes were compared between octogenarians (n = 339) and patients <80 years of age (n = 2,827).

RESULTS:

Baseline characteristics revealed a higher prevalence of females (P < 0.001), Caucasians (P = 0.004), chronic renal failure (P < 0.001), heart failure (P < 0.001), number of diseased vessels (P = 0.009), and lower ejection fraction (P = 0.03) in octogenarians. Patients <80 years showed more positive family history (P < 0.001), hyperlipidemia (P = 0.006), smoking (P < 0.001), and obesity (P < 0.001). Clinical presentation and procedural success were similar in both groups as were death, myocardial infarction (MI), and repeat revascularization in-hospital. At 6 months, restenosis rates were low and comparable. In the subgroup of octogenarians who presented with acute coronary syndrome, mortality (15% vs. 3%, P < 0.001) and Q-wave MI occurred more often. Multivariate analysis revealed age >80 (P = 0.008), cardiogenic shock (P < 0.001), Q-wave MI at presentation (P = 0.003), and length of hospital stay (P = 0.003) to be independent predictors of mortality.

CONCLUSIONS:

PCI with DES in octogenarians results in a similar reduction of restenosis rates when compared to patients <80 years. Yet in octogenarians who presented with acute coronary syndrome, incidence of mortality and Q-wave MI at 6 months was higher as compared to younger patients.
